The grain size, and therefore the grain boundary density, is known to play a major role in the
flow stress of metallic materials. A linear relationship to the inverse of the square root of the …

Abstract Bulk nanostructured (ns)/ultrafine-grained (UFG) metallic materials possess very
high strength, making them attractive for high strength, lightweight and energy efficient …

Bulk nanostructured (NS) materials processed by severe plastic deformation (SPD) have
received considerable attention for several decades. The physical origin of this processing …

Several pure metals (magnesium, aluminum, iron, cobalt, nickel, copper, zinc, palladium and
silver) and single-phase Al–Mg, Al–Ag, Al–Cu, Cu–Al, Cu–Zn, Pd–Ag, Ni–Fe and Ni–Co …

Tuning stacking fault energy (SFE) via alloying provides a robust protocol to manipulate
deformation mechanism and consequently the mechanical properties of metallic materials …

Abstract The AlFeCoNiBx (x= 0, 0.05, 0.10, 0.15, 0.2) high entropy alloys are prepared by
vacuum arc melting. The effect of B on the microstructure and mechanical behaviors of the …

An ideal ultrafine-grained (UFG) microstructure for high strength and high ductility should
have short dislocation-slip path to impede dislocation slip and very low dislocation density to …

High purity copper was processed by high-pressure torsion (HPT) at room temperature and
then stored at room temperature for periods of up to 6 weeks to investigate the effect of self …

In this work, a novel method based on pulsed-current-assisted vacuum sintering processes
was employed to fabricate the Cu/Al laminated metal composites (LMCs) with outstanding …

To address the trade-off between strength and electrical conductivity, we propose a strategy:
introducing precipitated particles into a structure composed of deformation twins. A Cu-0.3 …
